Improvement in trusses



UNITED STATES PATENT OFFICE.

LEWIS B. WHITE, OF MOSCOW, NEW YORK.

IM PROVEM ENT IN TRUSSES.

Specicaton forming part of Letters Patent No. 53,5 13, dated March 27,1866; antedated September 27, 1865.

To all whom it may concern:

Be it known that I, LEwIs B. WHITE, of Moscow, in the county ofLivingston and State of New York, have invented a new and usefulImprovement in Trusses used in Gases of Hernia; and I do hereby declarethat the following is afull and exact description thereof, referencebeing had to the accompanying drawings, making part of this specication-Figure l representinga top view ofthe truss Fig. 2, a front elevationthereof.

Like letters designate corresponding parts A in both figures.

This invention is designed as an improvementon the hernial truss forwhich Letters Patent of the United States were granted to Ine on the21st day ot August, 1860.

The construction and arrangement of the bow b and spring s aresubstantially the same as in my previous patent, except in the manner ofconnecting them with the lever Z, which supports the pad p. In theformer patent the lever was pivoted transversely on the end ot' the bowby means of a single pivot-pin projecting lengthwise from the bow; but,besides the liability of a single pivots breaking or bending from theright direction, that construction did not permit any transverseadjustment of the inclination or angle ot' bearing to be given to thepad to suit different patients and locations-of the hernia.

To obviate the above defects in the present invention two bearings, o o,are employed, which are situated obliqnely upward at an angle oftwenty-three and one-half degrees (more or less) to the end of the bow,and the padlever l is pivoted between the bearings, a screw passingthrough the bearings to form the pivot-pin for the lever. The end of thespring is so formed as to hook into the eye in the short end of thelever, which is bent to an obtuse angle, to suit the position of thespring and give the proper direction to the action ot' the pad. addstrength, rmness, and durability to the pivot connection between thefbowand padlever, but the angular position of these bearings is such thatthe pad can be varied in inclination or the direction of its pressure bymerely twisting the bow b slightly, so as just to suit the wearer andmake the truss iit easy.

To a projection ofthe long arm of the padlever a pin is attached, asshown, the head ot' which serves as a button to secure the cover to thetruss.

I do not claim the mere duplication of bearings; but

What'I claim as Iny invention, and desire to secure by Letters Patent,is-

The two pivot-bearin gs o o, arranged at an angle to the end ofthe bowin relation to the bow and pad-lever, substantially as and for thepurpose herein specified.
